How can I effectively reduce the risk of breakage for 200mm diameter graphite electrodes?
Reducing breakage risk requires both operational and material considerations:
• Standardized operation: Avoid mechanical collisions between the electrode and irregular scrap or the furnace wall; control the heating rate to reduce thermal stress.
• Proper connection: Ensure the electrode joints are clean and tightened to the specified torque, ensuring a vertical and tight connection to avoid additional stress caused by poor connections.
• High-quality products: Choose high-power (HP) or ultra-high-power (UHP) graphite electrodes with high strength and excellent thermal shock resistance.
